Benefits of technology

[0009]It is therefore an object of the invention, to provide an improved drug delivery device for dispensing of a dose of a medicinal product, which is particularly easy and secure in handling. It is a further object of the invention to provide an effective means for permanently informing the user of proper and unambiguous device handling as well as to provide product related or therapy related information. Moreover, the drug delivery device should be inexpensive in production and should further be mechanically stable and robust.SUMMARY OF THE INVENTION

Problems solved by technology

Further, the device should be inexpensive to manufacture and unproblematic to dispose.
In practice, such instruction manuals may easily get lost, in particular during a long-term use of refillable or reusable drug delivery devices.
In such cases, where the instruction manual for the device or other device- or medicinal product-related information is untraceable, the risk of inappropriate handling of the drug delivery device increases.
Any such inappropriate handling may imply an inappropriate and incorrect setting and dispensing of a dose, with e.g. serious consequences for the user or patient.
This endangerment even increases in such circumstances, where the patient has to deal with a plurality of different types of drug delivery devices or in cases, where a person other than the patient has to administer a predefined dose.

first embodiment

[0057]In FIGS. 1 and 2, the invention is illustrated. A housing component 100, which may either serve as housing for a dose dispensing mechanism or as a cartridge retaining part of a housing of a drug delivery device houses a rotatably mounted inner sleeve 108. The housing element 100 and the inner sleeve 108 have a circular cross-section, such that the inner sleeve 108 is free to rotate around the sleeves' 100, 108 long axes.

[0058]The display element 102 has a sheet-like contour and geometry is adapted to be rolled up on the inner sleeve 108 as illustrated in FIG. 2. Hence, in the rolled up configuration according to FIG. 2, the flexible and rollable display element 102 is wrapped around the outer circumference of the inner sleeve 108.

[0059]The housing component 100 further comprises at least a longitudinal slit 112, as illustrated in FIG. 2, allowing the display element 102 to be drawn off in radial direction. For this purpose, at its free end section, the display element 102 comp...

second embodiment

[0065]The second embodiment according to FIG. 3 exemplary shows a display element 202 comprising a rather stiff and non-flexible behaviour. Here, the display element 202 comprises a sleeve-like geometry with a radially outwardly protruding rib 204. The display element 202 is slidably disposed relative to the housing component 202. This interleaved arrangement allows for a relative axial displacement in order to reveal or to conceal the information provided on the outer circumference of the display element 202.

[0066]In this embodiment, the display element 202 itself may act as a housing component, whereas the housing component 200 may serve as a slidable cover for the information printed on the display element 202. In this embodiment, either one of display element 202 or housing component 200 may be connected to a further, not particularly illustrated housing component of the drug delivery device, which for instance contains a dose dispensing mechanism (not illustrated) or a cartridg...

third embodiment

[0069]The third embodiment illustrated in FIGS. 5 and 6 provides a foldable display element 102, that comprises regularly spaced fold lines 310 extending in longitudinal direction, i.e. parallel to the housing component's 300 long axis. Whereas the unfolded configuration is illustrated in FIG. 5, the folded and hidden configuration of the display element 302 is exemplary illustrated in FIG. 6. As can be seen, the foldable sheet-like display element 302 is adapted to be folded in a zig-zag-like manner. Consequently, adjacent sections of the display element 302 that are separated by a fold line 310 are arranged on top of each other in the folded not explicitly illustrated configuration of FIG. 6.

[0070]As can be further seen in detail in FIG. 5, the housing component 300 integrally comprises a receptacle 308 of a somewhat rectangular shape for receiving the folded display element 302. As its free end, which points away from the inner section of the housing component 300, the display el...

Abstract

The present invention relates to a drug delivery device for dispensing of a dose of a medicinal product, comprising:a housing having at least one housing component (100; 200; 300)a cartridge comprising the medicinal product,a dose dispensing mechanism operably engaged with the cartridge for setting and / or dispensing of a predefined dose of the medicinal product, anda display element (102; 202; 302) being movably disposed relative to the at least one housing component (100; 200; 300), whereinthe display element (102; 202; 302) and the housing component (100; 200; 300) are mutually moveable for selectively concealing and / or revealing information provided on the display element (102; 202; 302).

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is a 35 U.S.C. 371 National Application of PCT / EP2010 / 053966 filed Mar. 26, 2010, which claims priority to European Patent Application No. 09004571.7, filed Mar. 30, 2009, and also claims priority to U.S. Provisional Patent Application No. 61 / 169,849, filed Apr. 16, 2009, the entire contents of which are incorporated entirely herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to drug delivery devices and in particular to pen-type injectors, wherein a medicinal product can be administered.BACKGROUND AND PRIOR ART[0003]User operated drug delivery devices are as such known in the prior art. They are typically applicable in circumstances, in which persons without formal medical training, i.e. patients, need to administer an accurate and predefined dose of a medicinal product, such as heparin, insulin or the like. In particular, such devices have application, where the medicinal product is adm...
